If you only need a count, I'd avoid Split() -- it takes up unnecessary space. Perhaps:

static int WordCount(string s)
{
    int wordCount = 0;
    for(int i = 0; i < s.Length - 1; i++)
        if (Char.IsWhiteSpace(s[i]) && !Char.IsWhiteSpace(s[i + 1]) && i > 0)
            wordCount++;
    return ++wordCount;
}

public static void Main()
{
    Console.WriteLine(WordCount(" H elloWor    ld g  ")); // prints "4"
}

It counts based on the number of spaces (1 space = 2 words). Consecutive spaces are ignored.
